WITH 20 × 100/1000BASE-FX SFP + 4 X GIGABIT COMBO
+ 4 × 1000BASE-FX SFP PORTS
v1.0 February 12, 2019
The ComNet CWGE28MS2 has twenty 100/1000Base-FX SFP ports, four Gigabit
combo ports that allow for TX or FX transmission and four 1000Base-FX SFP ports.
All SFP ports utilize ComNet SFP modules for fiber, connector type and distance. The
IEEE802.3-compliant unit offers multiple Ethernet redundancy protocols (ERPS G.8032
and MSTP/RSTP/STP) which protect your applications from network interruptions
or temporary malfunctions by redirecting transmission within the network. The
CWGE28MS implements complete Layer 2 to Layer 4 ACLs to restrict access to your
sensitive network resources by filtering specific packets based on TCP/UDP ports,
source and destination IP addresses or particular network devices. Furthermore,
DHCP snooping, TACACS+, ARP, IEEE 802.1X and Port Security provide additional
tools to manage access and levels of use of the network. These defence mechanisms
of the CWGE28MS along with advanced DoS auto prevention deliver robust network
security and enables network administrators to offer more stable services on a more
secure network.

100FX/1000Base-SX/LX SFP Ports
The 100/1000Base-SX/LX (SFP) ports support network speeds of 100Mbps or 1000Mbps, and is
designed to house 100Mbps/Gigabit SFP modules.
Gigabit Combo
There are four Gigabit Combo ports on the CWGE28MS. Combo ports have both an RJ-45
interface and an SFP slot, of which one can be in use at any one time. The RJ-45 ports operate at
10/100/1000 Mbps, while the SFP ports are capable of operating at 100Mbps or 1000 Mbps.
The Gigabit copper ports have the same number as its corresponding SFP slot. This means that
once an SFP slot is connected, the correspondingly numbered RJ-45 port (21, 22, 23 or 24) will not
function

INSTALLATION AND OPERATION MANUAL CWGE28MS
TECH SUPPORT: 1.888.678.9427
Installation
The location chosen for installing the Switch may affect its performance. When selecting a site, we
recommend considering the following rules:
Install the Switch in an appropriate place. See Technical Specifications for the acceptable
temperature and humidity ranges.
Install the Switch in a location that is not affected by strong electromagnetic field generators (such
as motors), vibration, dust, and direct sunlight.
Leave at least 10 cm of space at the front and rear of the unit for ventilation.
Desktop Installation
Follow the instructions listed below to install the Switch in a desktop location.
Locate the Switch in a clean, flat and safe position that has convenient access to AC power.
Affix the four self-adhesive rubber pads to the underside of the Switch.
Apply AC power to the Switch (The green PWR LED on the front panel should light up).
Connect cables from the network partner devices to the ports on the front panel (The green LNK
LED on the upper right of the port should light).
Warning: Because invisible laser radiation may be emitted from the aperture of the port when no
cable is connected, avoid exposure to laser radiation and do not stare into open apertures.
Mounting on a Rack
Attach brackets to each side of the switch and place the brackets in the racks slots. Insert and
tighten screws to securely attach the bracket to the rack on each side.
Getting Connected
The Switch is capable of connecting up to 24 network devices in fiber connection at Fast Ethernet,
or Gigabit Ethernet speeds.

INSTALLATION AND OPERATION MANUAL CWGE28MS
TECH SUPPORT: 1.888.678.9427
Powering On the Unit
The Switch uses an AC power supply 100~240VAC, 50~60 Hz. The Switchs power supply
automatically self-adjusts to the local power source and may be powered on without having any or
all LAN segment cables connected.
» Insert the power cable plug directly into the receptacle located at the front of the device.
» Plug the power adapter into an available socket.
Note: For international use, you may need to change the AC power adapter cord. You must use
a power cord set that has been approved for the receptacle type and electrical current in your
country.
» Check the front-panel LEDs as the device is powered on to verify that the Power LED is lit. If
not, check that the power cable is correctly and securely plugged in.
Installing the SFP modules and Fiber Cable
» Slide the selected SFP module into the selected SFP slot (Make sure the SFP module is aligned
correctly with the inside of the slot)
» Insert and slide the module into the SFP slot until it clicks into place
» Remove any rubber plugs that may be present in the SFP module’s mouth
» Align the fiber cable’s connector with the SFP module’s mouth and insert the connector
» Slide the connector in until a click is heard
» If you want to pull the connector out, first push down the release clip on top of the connector
to release the connector from the SFP module.
To properly connect fiber cabling: Check that the fiber terminators are clean. You can clean
the cable plugs by wiping them gently with a clean tissue or cotton ball moistened with a little
ethanol. Dirty fiber terminators on fiber optic cables will impair the quality of the light transmitted
through the cable and lead to degraded performance on the port.
Note: When inserting the cable, be sure the tab on the plug clicks into position to ensure that it is
properly seated.
Check the corresponding port LED on the Switch to be sure that the connection is valid. (Refer to
the LED chart).

INSTALLATION AND OPERATION MANUAL CWGE28MS
TECH SUPPORT: 1.888.678.9427
Connecting a Copper Cable
The RJ-45 Ethernet port fully supports auto-sensing and auto-negotiation.
» Insert one end of a Category 3/4/5/5e (see recommendation above) type twisted-pair cable
into an available RJ-45 port on the Switch and the other end into the port of the network node.
» Check the corresponding port LED on the Switch to ensure that the connection is valid. (Refer
to LED chart)
Connecting to the Console
The console port (DB-9) provides the out-of-band management facility. Use null modem cable to
connect the console port on the Switch and the other end into the COM port of the computer.
Connecting to Computer or a LAN
You can use Ethernet cable to connect computers directly to the switch ports. You can also
connect hubs/switches to the switch ports by Ethernet cables. You can use either the crossover or
straight-through Ethernet cable to connect computers, hubs, or switches.
Notice: Use a twisted-pair Cat5e Ethernet cable to connect the 1000BASE-T port otherwise the
link speed will not be able to reach 1Gbps.
